Hi Ramith/Prabath, Asitha and myself tested the CQL upgrade and found that there a is a dependency issue with hector as it required cassandra thrift dependency. Previously, older version of CQL needed Cassandra as a dependency which includes thrift. With the latest upgrade, we CQL does not depend on Cassandra and can be used as it is because of it's already a OSGi bundle. Since cassandra thrift needed for hector, I have created orbit bundle for cassandra-thrift version 1.2.13.wso2v4. Previous versions of cassandra thrift has some issues with their dependencies.
Pull request in [1] needs to merge and deploy before upgrading the CQL version in data reader component.
